Abstract

A heat dissipation module with twin centrifugal fans is described. The heat dissipation module is utilized in an electrical equipment and especially for a computer server system. The heat dissipation module has a honeycomb panel, a first fan, an air duct, a second fan and a plurality of sliding rails. The honeycomb panel connects with an outlet of the first fan and an out of the air duct in the rear side thereof. The first fan sucks hot air from the underside thereof and exhausts the hot air to the outside through the honeycomb panel. The second fan sucks hot air from the underside thereof and exhausts the hot air to the outside through the honeycomb by way of the air duct. The sliding rails configure along the two sides of the first fan and the second fan.
